5.13 Pump management

To control the circulation pumps for the heating circuits (UP1 and UP2), reed relay outputs can be used instead of the relay output. Depending on the operating state, the circulation pumps run during the times-of-use regulated depending on the differential pressure. The differential pres- sure is regulated by the pumps. Outside the times-of-use the circulation pumps are switched back to the minimum speed. The binary outputs BA1 to BA4 have the following function:

￿BA1, BA3: Circulation pump on and off

￿BA2, BA4: Reduce pump speed

If the circulation pump is to be switched on, the contact of BA1 or BA3 is closed. The binary out- puts BA2 and BA4 can be configured over the function blocks Co1, 2 -> Fb13.

￿Co1, 2

-> Fb13 = ON:

BA2, BA4 = OFF outside the time-of-use

￿Co1, 2

Note!

Refer to the pump manufacturer instructions for the exact terminal assignments of pumps since the terminal assignments vary depending on the pump.

In systems Anl 3, 5, 8 and 10, the pumps of an uncontrolled heating circuit can be switched on and off over an external binary signal. For this purpose, deactivate the Potentiometer input function (Co1 to Co3 -> Fb12 = OFF) and select the function block parameter FrG-E.
